Infineon implements TrenchStop IGBT7 in standard package
Infineon has implemented its TrenchStop technology in the industry standard EconoDual 3 package for medium power applications. The TrenchStop IGBT7 is based on micro-pattern trench technology enabling the 1,200V module to provide a leading nominal current of 900A enabling a 30 per cent higher inverter output current for the same frame size compared with the earlier technology, reports Infineon.
The micro-pattern TrenchStop IGBT7 trench technology performs with much lower static losses compared to the IGBT4, confirms Infineon. Its on-state voltage is reduced by up to 30 per cent for the same chip area. This brings significant loss reduction in the application, especially for industrial drives, which usually operate at moderate switching frequencies. The module can also be implemented in designs for commercial, construction and agricultural vehicles (CAV), servo drives, as well as solar and uninterrupted power supplies (UPS) inverters.
Improvements to the oscillation behaviour and the controllability of the IGBT allow a maximum overload junction temperature of +175 degrees C.
Another improvement is that the freewheeling diode (FWD) has been optimised for drive applications. The forward-voltage drop of the emitter-controlled seventh generation diode (EC7) is now 100mV lower than the forward-voltage drop of the EC4 diode, with reduced oscillation tendency during diode turn-off.
The higher power density of the EconoDual 3 helps to avoid paralleling of modules, which leads to a simplification of the inverter design and lower costs.
The new technology can be implemented in the same footprint facilitating the upgrade of existing inverter system designs. The EconoDual 3 module’s housing is available with pre-applied thermal interface material (TIM) for lowest thermal resistance and longest lifetime. The PressFIT housing enables a fast and cost-efficient assembly.
The 900A module is the first from Infineon’s new EconoDual 3 portfolio featuring TrenchStop IGBT7. Further module types / current classes will follow in 2020. The lead type FF900R12ME7_B11 can be ordered now. The FF900R12ME7P_B11 with pre-applied TIM will be available by January 2020.
